Abstract
Abstract A die plate organization for use on an extruder for puffed corn products and the like for producing straight rectangular French Fry-style puffed food products. The die organization includes a die plate having an array of orifices each of which is generally X-shaped in cross-section. A sleeve having an array of elongated passages generally square in cross-section is secured to the front of the die plate with the X-shaped orifices corresponding generally to the diagonals of the square cross-section of the passages. Puffed cereal grains and the like are extruded from the die plate through the passages to produce an elongated generally straight square puffed product.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A die plate organization for use with an extrusion machine for liquifying and extruding foodstuffs, comprising, in combination: a. a die plate mounted on an extrusion machine and having a circular array of extrusion orifices extending therethrough and opening into the outer face of said die plate, each outer face orifice opening being X-shaped in configuration; b. a guide sleeve means secured to the outer face of said die plate, said guide sleeve defining a plurality of substantially square passages corresponding in number to said die plate orifice openings, said square passages each being axially aligned with a corresponding X-shaped die plate orifice, the angular relationship of each said square passage and corresponding orifice being such that the X-shaped die orifice corresponds to the diagonals of the square passage.
Claim 2
Dependent Claim
129 words
A die plate organization for use with an extrusion machine for liquifying and extruding foodstuffs, comprising, in combination: a. a die plate mounted on an extrusion machine and having a circular array of extrusion orifices extending therethrough and opening into the outer face of said die plate, each outer face orifice opening being X-shaped in configuration; b. a guide sleeve means secured to the outer face of said die plate, said guide sleeve defining a plurality of substantially square passages corresponding in number to said die plate orifice openings, said square passages each being axially aligned with a corresponding X-shaped die plate orifice, the angular relationship of each said square passage and corresponding orifice being such that the X-shaped die orifice corresponds to the diagonals of the square passage.
Claim 3
Dependent Claim
159 words
A die plate organization for use with an extrusion machine for liquifying and extruding vegetable foodstuffs for producing straight elongated puffed sticks having a substantially square cross-section, said die plate organization comprising, in combination: a. a die plate mountable on an extrusion machine and having an array of extrusion orifices extending therethrough, said orifices opening into the outer face of said die plate, the outer face opening of each said orifice being of substantially X-shaped configuration; b. guide sleeve means secured to the outer face of said die plate and defining an array of axially extending passages corresponding in number to the orifices in said die plate, and with each such passage being axially aligned with a corresponding die plate orifice; c. each of said passages being substantially square in cross-section, with each square passage and its corresponding X-shaped orifice being aligned with the orifice legs extending generally diagonally with respect to the square cross-section of the corresponding passage.
Claim 4
Dependent Claim
159 words
A die plate organization for use with an extrusion machine for liquifying and extruding vegetable foodstuffs for producing straight elongated puffed sticks having a substantially square cross-section, said die plate organization comprising, in combination: a. a die plate mountable on an extrusion machine and having an array of extrusion orifices extending therethrough, said orifices opening into the outer face of said die plate, the outer face opening of each said orifice being of substantially X-shaped configuration; b. guide sleeve means secured to the outer face of said die plate and defining an array of axially extending passages corresponding in number to the orifices in said die plate, and with each such passage being axially aligned with a corresponding die plate orifice; c. each of said passages being substantially square in cross-section, with each square passage and its corresponding X-shaped orifice being aligned with the orifice legs extending generally diagonally with respect to the square cross-section of the corresponding passage.
Claim 5
Dependent Claim
52 words
A die plate organization as defined in claim 2 wherein the legs of said X-shaped orifice openings extend at right angles with respect to each other, and the ratio of the length to the width of each leg being about 4 to 1 and with the legs being of substantially uniform width.
Claim 6
Dependent Claim
33 words
A die plate organization as defined in claim 2 wherein the ratio of the cross-sectional area of the square passage to the cross-sectional area of the X-shaped die orifice is about 20 to
Claim 7
Dependent Claim
72 words
A die plate organization as defined in claim 2 wherein said guide sleeve comprises an inner sleeve member having a plurality of axially extending slots with the side walls defining each slot being parallel to each other and with said side walls being perpendicular to the bottom wall of the slot, and an outer sleeve member surrounding and enclosing said slots thereby to define a plurality of passages substantially square in cross-section.
